Versuchsvorschrift

1-(4-Hydroxyphenoxy)-4-nitrobenzene X (8.93 g, 38.62 mmol), 0.5% platinum catalyst on activated charcoal (1.5 g), THF (100 mL), and ethyl acetate (20 mL) were charged into a 250 mL hydrogenation vessel. Hydrogenation was carried out under 60 psi of hydrogen at room temperature for 16 hr. The reaction mixture was filtered and the organic solvents were removed under reduced pressure at 40° C. to give 4-(4-aminophenoxy)phenol XI (8.10 g, 96.2% yield), mp 130°-4° C. The IR and 1H-NMR spectra agreed with the assigned structure.
